Combine all the ingredients except the coconut oil in a food processor and process for 3 to 5 minutes until chopped to a fine consistency. Transfer the mixture to a mixing bowl. Add the melted coconut oil and stir until well combined. Form into 1-inch round balls and place on waxed paper. Refrigerate for 15 to 20 minutes, then transfer to an airtight container. The balls will keep for 2 weeks, refrigerated.
